Quick post today around setting exchange online max send and receive size. It can be set using the GUI in mailbox properties. I prefer to use powershell when I can.
First make sure you have the latest exchange online powershell module installed.
Then connect to exchange
Connect-ExchangeOnline
if you want to see all mailboxes to the same size, use this command
Get-Mailbox | Set-Mailbox –MaxSendSize 150 MB –MaxReceiveSize 150 MB
Don’t forget to update your mailbox plan so all new mailboxes have the updated limit.
Get-MailboxPlan | Set-MailboxPlan –MaxSendSize 150MB –MaxReceiveSize 150MB
you can confirm and individual mailbox size with
get-mailbox -Identity <UserName> | fl name, MaxSendSize, MaxReceiveSize
or get a csv of all mailboxes
Get-Mailbox -ResultSize 2500| Select-Object Name,MaxSendSize,MaxReceiveSize| Export-CSV -NoTypeInformation -Path "$ENV:UserProfile\desktop\mailboxes.csv"
